The plant claimed shall be known as ‘SV30-27-602’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of grapevinebotanically known as Vitis vinifera and hereinafter referred to asgrapevine named ‘SV30-27-602’. As used herein, ‘grapevine’ refers to allplant parts including vines, canes, tendrils, leaves, fruit and roots of‘SV30-27-602. Grapevine named ‘SV30-27-602’ is the result of an effortto produce a late ripening red, seedless table grape with fruitcharacteristics superior to currently available cultivar ‘Scarlet Royal’(U.S. Plant Pat. No. 16,229). This cultivar resulted from a cross madein April 2009 between female grapevine named ‘SV16-76-232 (unpatented)and male grapevine plant named ‘SV21-66-226’ (U.S. Plant Pat. No.24,531). Resultant seeds were harvested in October 2009 and werestratified under refrigeration at 2 degrees Celsius. The seeds wereplanted in soil in the greenhouse in January 2010 and resultantseedlings were grown in the greenhouse until April 2010. The seedlingswere transplanted to a field north of Delano, Calif. in that same monthand were trained to a trellis that same year. Fruit of the seedling wereobserved on Aug. 9, 2013 at which time the selection for trialling wasmade. Woody cuttings were harvested in December of 2013 and buds ofgrapevine named ‘SV30-27-602’ were bench grafted to ‘Freedom’(unpatented) rootstock. The resultant plants were planted in a triallocation near McFarland, Calif. in May of 2014 and were trained to at-trellis on 7 foot by 10 foot spacing. The present invention has beenfound to retain its distinctive characteristics through three successivepropagations.

Grapevine named ‘SV30-27-602’ differs from its female parent, grapevinenamed ‘SV16-76-232’ (unpatented), in that ‘SV30-27-602 isstenospermocarpic with small seed traces while ‘SV16-76-232’ has fullydeveloped, functional seeds.

Grapevine named ‘SV30-27-602’ differs from its male parent,‘SV21-66-226’ (U.S. Plant Pat. No. 24,531), in that ‘SV30-27-602’produces red skinned ellipsoidal grapes while ‘SV21-66-226’ producesgreen skinned grapes.

Grapevine named ‘SV30-27-602’ most closely resembles ‘Scarlet Royal’(U.S. Plant Pat. No. 16,229) but it may be distinguished from ‘ScarletRoyal’ because ‘SV30-27-60 produces berries with a much brighter redcolor than the dark red berries produced by ‘Scarlet Royal’.Additionally, grapevine named ‘SV30-27-602’ produces berries withdistinct muscat flavor and no astringency while ‘Scarlet Royal’ (U.S.Plant Pat. No. 16,229) berries develop astringency at full ripeness.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices near McFarland, Calif.

-   -   1. Red skinned berries;    -   2. Firm berry texture; and    -   3. Large, ellipsoidal shaped berries with muscat flavor.

BRIEF DESCRIPTION OF THE DRAWINGS

This new grapevine is illustrated by the accompanying photographs whichshow fruit clusters, leaves, canes and tendrils. The colors shown are astrue as can be reasonably obtained by conventional photographicprocedures. The photographs were taken from plants about 5 years old,grown in a field near McFarland, Calif. in 2019.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctivecharacteristics of grapevine named ‘SV30-27-602’. Descriptions of thenew invention apply to vines of grapevine named ‘30-27-602’ grown on‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectaregrown near McFarland, Calif. in 2019. These vines were in their fourthyear of full production having been planted in 2014. These descriptionsare believed to apply generally to the new variety grown under similarcircumstances elsewhere.
